I wanted to take a single picture with
raspistill, but it writes a file every ~11 seconds and does not stop. The command is:
raspistill -t 0 -q 90 -dt -w 1920 -h 1080 -n -fli 50hz -o /media/pi/Timelapse/image%d.jpg
and IMHO, this is, what it should do:
-t 0: take the picture immediately (remove the default delay of 5s)
-q 90: set the quality to 90
%din the file name by month, day, hour, minute and second. This works, the files have a name like that.
-w 1920 -h 1080: take the picture at FullHD. This works, the saved pictures have that size.
-n: do not show a preview window
-fli 50hz: set the mains frequency for flicker removal
-o /media/pi/Timelapse/...: save the image on external hard drive. This also works, the files are in that folder.
I don't see why this command would run forever and not stop after it took the photo. How do I take one photo only?
